Controlling carbon emissions to achieve green and sustainable development has become a global consensus and general trend. China established “30.60” decarbonization goal for carbon peak and carbon neutrality in 2019. As electromechanical energy conversion devices, the electrical machines and systems play important roles in both renewable energy harvesting, such as wind, tidal, ocean current energy, etc., and new energy drive, such as electric vehicle, more electric aircraft, and more electric ship, etc. However, the improvement of their power density, efficiency, and reliability faces many new challenges in the background of new energy applications. How to further improve these performances from the aspects of novel topologies, intelligent optimization methods, advanced control strategy, online fault diagnosis and health management, etc., becomes a key issue to promote applications of electrical machines and systems in the new energy area.
